Workers in the Shreveport-Bossier City Metropolitan Statistical Area had an average (mean) hourly wage of $17.99 in May 2013, about 19 percent below the nationwide average of $22.33, according to the U.S. Bureau of Labor Statistics. Regional Commissioner Stanley W. Suchman noted that, after testing for statistical significance, local wages were significantly lower than their respective national averages in 17 of the 22 major occupational groups, including legal; computer and mathematical; and sales and related occupations. Wages were higher in one group, farming, forestry, and fishing, while wage levels in the four remaining groups were not statistically different from their respective national averages.
When compared to the nationwide distribution, local employment was more highly concentrated in 9 of the 22 occupational groups, including healthcare practitioners and technical; construction and extraction; and installation, maintenance, and repair. Conversely, ten groups had employment shares significantly below their national representation, including business and financial operations; computer and mathematical; and production. (See table A and box note at end of release.)

(1) A positive percent difference measures how much the mean wage in Shreveport-Bossier City is above the national mean wage, while a negative difference reflects a lower wage.
One occupational group–construction and extraction–was chosen to illustrate the diversity of data available for any of the 22 major occupational categories. Shreveport had 8,940 jobs in construction and extraction, accounting for 5.2 percent of local area employment, significantly higher than the national share of 3.8 percent. However, the local wage for this occupational group was significantly below the U.S. average. At $18.22 an hour, the mean wage for Shreveport construction and extraction workers was 17 percent below the $21.94 national average.
With employment of 1,190, construction laborers was among the largest occupations within the construction and extraction group, as were carpenters (900), electricians (790), and plumbers, pipefitters, and steamfitters (790). Among the higher paying jobs were first-line supervisors of construction trades and extraction workers, as well as plumbers, pipefitters, and steamfitters, with mean hourly wages of $27.34 and $21.47, respectively. At the lower end of the wage scale were construction laborers ($13.25) and oil and gas roustabouts ($14.84). (Detailed occupational data for construction and extraction are presented in table 1; for a complete listing of all detailed occupations, see www.bls.gov/oes/current/oes_43340.htm.)
Location quotients allow us to explore the occupational make-up of a metropolitan area by comparing the composition of jobs in an area relative to the national average. (See table 1.) For example, a location quotient of 2.0 indicates that an occupation accounts for twice the share of employment in the area than it does nationally. In the Shreveport metropolitan area, above average concentrations of employment were found in many of the occupations within the construction and extraction group. For instance, oil and gas roustabouts were employed at 4.3 times the national rate in Shreveport, and oil, gas, and mining service unit operators, at 7.3 times the U.S. average. On the other hand, construction laborers had a location quotient of 1.1 in Shreveport, indicating that this particular occupation’s local and national employment shares were similar.
These statistics are from the Occupational Employment Statistics (OES) survey, a federal-state cooperative program between BLS and State Workforce Agencies, in this case, the Louisiana Workforce Commission.
OES wage and employment data for the 22 major occupational groups in the Shreveport-Bossier City Metropolitan Statistical Area were compared to their respective national averages based on statistical significance testing. Only those occupations with wages or employment shares above or below the national wage or share after testing for significance at the 90-percent confidence level meet the criteria.
Note: A value that is statistically different from another does not necessarily mean that the difference has economic or practical significance. Statistical significance is concerned with the ability to make confident statements about a universe based on a sample. It is entirely possible that a large difference between two values is not significantly different statistically, while a small difference is, since both the size and heterogeneity of the sample affect the relative error of the data being tested.
The Occupational Employment Statistics (OES) survey is a semiannual mail survey measuring occupational employment and wage rates for wage and salary workers in nonfarm establishments in the United States. Guam, Puerto Rico, and the Virgin Islands are also surveyed, but their data are not included in the national estimates. OES estimates are constructed from a sample of about 1.2 million establishments. Forms are mailed to approximately 200,000 sampled establishments in May and November each year for a 3-year period. May 2013 estimates are based on responses from six semiannual panels collected in May 2013, November 2012, May 2012, November 2011, May 2011, and November 2010. The overall national response rate for the six panels is 75.3 percent based on establishments and 71.6 percent based on employment. The sample in the Shreveport-Bossier City Metropolitan Statistical Area included 2,118 establishments with a response rate of 74 percent. For more information about OES concepts and methodology, go to www.bls.gov/news.release/ocwage.tn.htm.
The OES survey provides estimates of employment and hourly and annual wages for wage and salary workers in 22 major occupational groups and 821 detailed occupations for the nation, states, metropolitan statistical areas, metropolitan divisions, and nonmetropolitan areas. In addition, employment and wage estimates for 94 minor groups and 458 broad occupations are available in the national data. OES data by state and metropolitan/nonmetropolitan area are available from www.bls.gov/oes/current/oessrcst.htm and www.bls.gov/oes/current/oessrcma.htm, respectively.
The May 2013 OES estimates are based on the 2010 Standard Occupational Classification (SOC) system and the 2012 North American Industry Classification System (NAICS). Information about the 2010 SOC is available on the BLS website at www.bls.gov/soc and information about the 2012 NAICS is available at www.bls.gov/bls/naics.htm.
The substate area data published in this release reflect the standards and definitions established by the U.S. Office of Management and Budget.
